A machine builder asks about the trade-offs between a switched mode power supply and linear regulated.

We’re trying to save cabinet space by changing from a linear regulated power supply to a switched mode power supply. From what I understand, we’ll get a higher power density with a smaller footprint, while the power factor is about the same. My biggest concern is, with so many devices offering built-in intelligence these days, will a switching power supply create so much electromagnetic interference that it will cause a controls problem on our form, fill and seal machines?
Any mounting recommendations to reduce EMI? What about unregulated? And how close are power supplies to offering their own control capabilities, or is that already available?

Imagine the gains in productivity and profitability you’ll realize when you connect machinery to the Industrial Internet of Things (IIoT). More information means smarter decisions. And collective intelligence is better than siloed data.

If the application dictates the device, does the device dictate the communication?

Question: We’ve been using resolvers to track motor-shaft position in the CNC machines we build for years. And no one has asked, so we’ve never considered changing that technology. But now a customer has requested we also utilize encoders. While the variety of encoder types—capacitive, magnetic, optical—is pretty straightforward, we’re having some discussions as we try to understand the communication protocols available and which direction to go.
Can I replace a resolver with a sin/cos encoder? What about Hiperface, EnDat, SSI? If the application dictates the encoder or resolver, does the device dictate the communication protocol?
Join in the discussion below.

Researchers Will Demonstrate Feasibility of Using Standardized 3D Models for Electronically Exchanging and Processing Product and Manufacturing Information

National Institute of Standards and Technology (NIST) researchers and their industrial partners have embarked on a Design to Manufacturing and Inspection Project to add a new dimension to manufacturing capabilities. They will demonstrate the feasibility—and benchmark the advantages—of using standardized, 3D models for electronically exchanging and processing product and manufacturing information all the way from design through inspection of the final part, a tightly integrated, seamless string of activities that manufacturers are calling a "digital thread.”
Tom Hedburg, one of the researchers in the project, explains, “What we’re talking about is a 3D drawing with all the product information embedded in it. It’s a way of…

Sometimes, choosing a component is up to the customer’s discretion. Sometimes, it’s based on the application. And sometimes it’s just what the machine builder is most familiar with. With relays, there are a few clear-cut ways to go, but many…

A machine builder wants to know the tradeoffs between stepper motors and servo motors for its CNC machines

We've been using stepper motors in the CNC machines we build. However, we sometimes lose steps because of the heavy table. We’ve considered putting a feedback device on the stepper application to optimize torque, but is there a better solution? Would a servo motor solve this? What are the tradeoffs?

Tablet-sized HMI builds on established features with modern resolution.

Two new tablet-sized HMI displays from Maple Systems bring an expanded operator field of vision and in-cabinet protection to the industrial marketplace. Enter the HMI5097XL and HMI5097NXL 9.7-in HMI displays.
A 70° viewing angle enables an improved field of vision for efficient monitoring and control of operational status. “These particular displays have an extremely wide viewing angle,” explains Larry St.Peter, CEO of Maple Systems. “It’s virtually from side to side. With previous HMI displays, if you went off-axis more than 30°, your ability to see what’s on-screen would go away. With these new displays, you get resolution all the way around, from almost every angle. The operator no longer has to stand directly in front of…

Are analog panel meters still good enough, or do we need to look at digital panel meters or the HMI-PLC combo units?

The textile machinery we build includes some wet process technologies. Analog panel meters have always done the job, but we’ve started looking at different options. Newer process designs have required greater accuracy and enabled closed-loop control on processes that previously required manual operation. We’re looking at higher-end digital panel meters, but each piece of equipment requires many, and they all require some degree of configuration. Because of the price, the costs mount quickly.
Are there digital-panel-meter options that will meet our needs without putting us at a price disadvantage with our competitors? Perhaps I could replace the panel meters with a PLC and HMI. I’ve also heard about the PLC-HMI combos with PID…

No Matter What Type of Switch is Used, It’s Important to Recognize and Account for the Needs of Engineering Staff, Maintenance Personnel and Operators to Access a Machine for Upkeep and Cleaning.

When you've got to stop, you've got to stop. For machine builders, that's usually a job for safety switches. They allow safe access to dangerous machines by putting systems in a harmless state, which could mean cutting off power completely. In selecting a safety switch, it's important to keep in mind frequency and function, according to Roberta Nelson Shea, global marketing manager for Rockwell Automation. For something that needs to be opened only once a year, the best solution likely is to use simple guards, such as by completely encasing the area. More frequent access has to be easier. It's when access is frequent, but not constant that an interlocking safety switch comes into play."You expect somebody needs to get in there at least…

Is there a glass ceiling in manufacturing, especially in machine building? Few women are seen across this field, and even fewer are present at the executive level.

If any industry has a glass ceiling, it is manufacturing in general and machine building in particular. There are few women at all levels of manufacturing, and executive representation is virtually nonexistent.

It begs the question of whether there really is a glass ceiling, a term that connotes a barrier imposed by men to keep women out of the executive suite. Are there other, perhaps even- more important, reasons why women arent running machine-builder and other manufacturing companies?

For a person to advance to a CEO position in manufacturing the first requirement generally is a technical degree foundation. That eliminates most women because theyre already woefully underrepresented in undergraduate technical degree programs.

The second requirement is a relentless focus on getting to the top at all costs. This means jettisoning less-important goals such as maintaining personal health, developing deep and meaningful relationships outside of work, and spending lots of time with family.

Men seem to have fewer qualms than women with abandoning a balanced lifestyle in favor of a one-dimensional focus on work.

Thats too bad because a single-minded pursuit of the top job usually yields failure. Do the math. There only is one top job per company, and the odds that a person will reach that spot are daunting. CEO fame and fortune might be great, but the expected dollar value for aspiring candidates is low because executive compensation must be reduced by that low probability of attaining the position.We can draw an analogy with sports. According to www.mlbplayers.com, the average salary of a major leaguer in 2006 was about $2.7 million.

But theres nothing average about a major leaguer, and few professional baseball players make it to The Show. The typical professional baseball player spends a few years in the minor leagues and makes about $20,000 a year. His expected lifetime earnings from playing baseball are considerably less than $100,000.

For less than $100,000, a young man spends tens of thousands of hours in minor league preparation, often bypassing college in the process.

If he enjoyed the journey, then hell conclude it was worth it. If he was in the game only to reach the top, hell end up disappointed. The same thing happens every day in the world of business. Many men forgo all else in pursuit of a long shot. Its a sucker bet. No wonder the gaming tables in Las Vegas are full of men.

I guess most women are too wise to make that bet. They pursue business success, but they do so in a manner that lets them maintain their health, their personal relationships, and their family ties.

They enjoy the journey and some of them make it to the top. For some evidence of that see a reprint of the ControlGlobal.com article The Ladies of the Club at ControlDesign.com/glassceiling.

The end result: women are healthier and happier than men by any measurable criteria. Women live about seven years longer. Men die by their own hand at four times the rate of women.

Around middle-age, many men realize they are not going to reach the executive suite. Years of accumulated work-related stress and an unhealthy, work-driven lifestyle combine with bitter disappointment to take a toll. The result is that in the 55-to-64-year-old age range more men than women die, due mainly to heart disease, suicide, car accidents, or illness related to smoking and alcohol use.

Most of us realize that family and friends are a comforting presence in old age. What if you spent the past 40 years neglecting both in pursuit of business success?

Its fine to strive to attain your professional goals, but enjoy the journey. If youre that rare person who can find complete personal satisfaction, health, and happiness in activities entirely related to work, youre well-suited to a single-minded CEO quest.

If you value other things in addition to business success, dont make that sucker bet.
